No file handy?

From one file to separate parts

Ideal for accessory sets, loose parts and grouped models. Try the sample to see how it works.

Separates disconnected surfaces without cutting or repairing the mesh. Up to 80 MB, 500,000 triangles and 1,000 components.

Every part, in its own file

Upload an STL containing multiple parts. Detect disconnected components, inspect them individually and download only what you need.

What this tool does

  • Find edge-connected components without cutting or changing triangles.
  • Select components by color, dimensions and triangle count.
  • Inspect the whole assembly or spread parts visually.
  • Download individual STLs or a ZIP containing all parts, retaining original coordinates.

How it works

  1. 01

    Load your STL

    Choose a file or try the five-part sample. Analysis can be cancelled.

  2. 02

    Select a part

    Use the list to isolate a component. Spreading only affects the preview.

  3. 03

    Download what you need

    Export the selection as an STL or all parts together in a ZIP.
